Abstract
The utility model discloses a kind of micrometer with pressure sensor, including arch chi frame, fixes sleeve, microdrum, device for measuring force, micrometric screw, gage button, also include pressure sensor and dynamometry display device, pressure sensor is disc, it is fixed on gage button surface, dynamometry display device is on arch chi frame, and pressure sensor is connected with dynamometry display device by wire.The utility model is conducive to the accurate chucking power for providing object under test, available for the improvement of existing micrometer, improves the accuracy of measurement.
Description
Technical field
The utility model is related to a kind of dimensional measuring instrument, specially a kind of micrometer with pressure sensor.
Background technology
Micrometer is a kind of length measuring instrument of more precision.During using micrometer, object under test (such as steel ball) is put
Between micrometric screw and gage button, rotation micrometric screw makes object under test while being contacted with micrometric screw and gage button, then rotates
Reading after the device for measuring force of micrometer afterbody clamps object under test.National metrological verification regulations of the China on micrometer
(JJG21-2008) provided in：The dynamometry of micrometer should be 5-10N.But in actually measurement, the size of device for measuring force applying power
Display is had no, thus easily causes the clamping degree of measuring targets and is differed, measurement error is thus produced, and bring to user
Inconvenience.
Utility model content
The purpose of this utility model, is the disadvantages mentioned above for overcoming existing micrometer, develop it is a kind of with pressure sensor thousand
Divide chi.
In order to solve the above-mentioned technical problem, the utility model is achieved through the following technical solutions：Including arch chi frame, fixation
Sleeve, microdrum, device for measuring force, micrometric screw, gage button；Also include pressure sensor and dynamometry display device, the pressure is passed
Sensor is disc, is fixed on gage button surface, and the dynamometry display device is on arch chi frame, and pressure sensor shows with dynamometry
Showing device is connected by wire.
The dynamometry display device is liquid crystal display.
The dynamometry display device is LED, when the pressure sensor is by pressure more than or equal to 5N, output letter
Number lightening LED lamp.
The utility model, in measurement, object under test is sandwiched between micrometric screw and gage button due to using above-mentioned design,
Device for measuring force is gently rotated, until dynamometry display device is shown as 5N, or LED is lighted, point out gauger to stop reinforcing, can be with
Reading.The utility model is conducive to the accurate chucking power for providing object under test, available for the improvement of existing micrometer, improve measurement
Accuracy.
Brief description of the drawings
The utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is composition schematic diagram of the present utility model.
In figure：1. arch chi frame, 2. fixes sleeves, 3. microdrums, 4. device for measuring force, 5. micrometric screws, 6. gage buttons, 7. pressures
Force snesor, 8. dynamometry display devices, 9. battery cases.
Embodiment
As shown in figure 1, the utility model includes arch chi frame 1, fixes sleeve 2, microdrum 3, device for measuring force 4, micrometer spiral shell
Bar 5, gage button 6, in addition to pressure sensor 7 and dynamometry display device 8.Pressure sensor 7 is disc, is fixed on gage button 6
Surface, dynamometry display device 8 is on arch chi frame 1, and pressure sensor 7 is connected with dynamometry display device 8 by wire.Gage button
6 afterbody is additionally provided with battery case 9, and button cell built in battery case 9 is that pressure sensor 7 and dynamometry display device 8 are powered.
Dynamometry display device 8 is liquid crystal display, the size for intuitively showing object under test chucking power.
Dynamometry display device 8 or LED, when pressure sensor 7 is by pressure more than or equal to 5N, output signal
Lightening LED lamp.
